Hive Import Fails After an HDFS Nameservice Change


Upon changing my nameservice, Datameer Hive jobs are failing to Import. The following error is displayed:

ERROR [2018-06-01 16:59:30.894] [JobScheduler thread-1] ( - Job 865 failed with exception.

java.lang.IllegalArgumentException: Wrong FS:hdfs://oldname/data, expected: hdfs://newname
